Le but de la présente invention est de perfectionner les appareils existants.The object of the present invention is to improve the existing apparatus.

A cet effet, l'invention a pour objet un distributeur de matériau d'essuyage prédécoupé, sous forme de bobine déroulable en bande, le distributeur comprenant : un carter, un couvercle mobile par rapport au carter entre une position ouverte et une position fermée, et un module reçu dans le carter ; le module étant partiellement recouvert par le couvercle en position fermée, en délimitant un passage de sortie de la bande de matériau ; le module comprenant :

  • deux parois latérales parallèles entre elles, entre lesquelles la bobine est positionnée,
  • un dispositif de guidage de la bande déroulée depuis la bobine,
  • un volet disposé transversalement entre les parois latérales, présentant deux bordures latérales qui s'étendent en regard des parois latérales, et une face avant comportant un profil en arc-en-ciel constitué de saillies et creux qui s'étendent chacun suivant un arc sur la face avant, et
  • une plaque disposée transversalement en avant du volet, mobile par rapport aux parois latérales entre une position abaissée et une position relevée, et présentant une face arrière comportant un profil en arc-en-ciel constitué de saillies et creux qui s'étendent chacun suivant un arc sur la face avant ;
le profil en arc-en-ciel du volet et le profil en arc-en-ciel de la plaque étant complémentaires, de sorte que les saillies du volet sont logées dans les creux de la plaque et les saillies de la plaque sont logées dans les creux du volet lorsque la plaque est en position relevée ;
le volet et la plaque délimitant ainsi entre eux un espace de guidage et serrage de la bande, présentant une configuration variable, et situé immédiatement en amont du passage de sortie de la bande ;
le module comprenant un système de débattement relatif entre le volet et la plaque, faisant varier la configuration de l'espace de guidage et serrage de la bande, le système de débattement comprenant :
  • quatre tiges transversales formées en saillie sur les bordures latérales du volet, avec deux tiges espacées par bordure latérale, et
  • quatre logements ménagés dans les parois latérales du module, avec deux logements par paroi latérale,
caractérisé en ce que chaque logement reçoit l'une des tiges du volet et comporte une partie longitudinale et une partie verticale, un jeu de débattement étant ainsi défini longitudinalement et verticalement entre chaque tige et le logement correspondant.For this purpose, the subject of the invention is a pre-cut wiper material dispenser, in the form of a strip-rollable reel, the dispenser comprising: a casing, a lid movable relative to the casing between an open position and a closed position, and a module received in the housing; the module being partially covered by the lid in the closed position, delimiting an outlet passage of the strip of material; the module comprising:
  • two parallel lateral walls between which the coil is positioned,
  • a device for guiding the strip unrolled from the reel,
  • a flap arranged transversely between the side walls, having two side edges which extend facing the side walls, and a front face having a rainbow profile consisting of projections and recesses which each extend in an arc on the front, and
  • a plate arranged transversely in front of the flap, movable relative to the side walls between a lowered position and a raised position, and having a rear face having a rainbow profile consisting of projections and recesses which each extend in an arc on the front face;
the rainbow profile of the shutter and the rainbow profile of the plate being complementary, so that the projections of the shutter are housed in the recesses of the plate and the projections of the plate are housed in the hollow of the shutter when the plate is in raised position;
the shutter and the plate thus delimiting between them a guiding space and tightening of the band, having a variable configuration, and situated immediately upstream of the exit passage of the strip;
the module comprising a system of relative movement between the flap and the plate, varying the configuration of the guiding space and tightening of the band, the deflection system comprising:
  • four transverse rods projecting from the lateral edges of the flap, with two rods spaced by lateral edge, and
  • four housings in the side walls of the module, with two housings per side wall,
characterized in that each housing receives one of the shutter rods and has a longitudinal portion and a vertical portion, a deflection clearance being thus defined longitudinally and vertically between each rod and the corresponding housing.

Ainsi, l'invention permet d'éviter le retour en arrière et la remontée de la bande de matériau, provoqués par le mouvement de balancier du dispositif de guidage. Ce mouvement de balancier survient lorsqu'un utilisateur exerce une force de tirage sur la bande de matériau, au niveau du passage de sortie. En pratique, ce mouvement de balancier est d'autant plus prononcé que l'utilisateur exerce une force de tirage importante.Thus, the invention avoids the return back and the rise of the web of material, caused by the rocking movement of the guide device. This pendulum movement occurs when a user exerts a pull force on the web of material at the exit passage. In practice, this pendulum movement is all the more pronounced as the user exercises a large pulling force.

Le système de débattement permet de resserrer temporairement l'espace délimité entre le volet et la plaque, et donc augmenter temporairement les forces de frottements exercées entre la bande, le volet et la plaque dans cet espace, lorsqu'un utilisateur tire sur la bande de matériau. En premier lieu, les forces de frottement sont conjuguées à la force de tirage pour séparer un format de la bande. En outre, ces forces de frottement empêchent la bande de remonter en direction de la bobine.The deflection system makes it possible to temporarily tighten the space defined between the shutter and the plate, and thus temporarily increase the friction forces exerted between the strip, the shutter and the plate in this space, when a user pulls on the strip of material. First, the friction forces are combined with the pulling force to separate a format from the web. In addition, these frictional forces prevent the band from rising towards the coil.

Ce système de débattement est efficace quel que soit la direction de la force de traction exercée par l'utilisateur. Le blocage anti-remontée de la bande se fait dans l'espace situé juste au-dessus du passage de sortie, à la verticale de la préhension et de la traction sur le format constituant l'extrémité de la bande.This travel system is effective regardless of the direction of the traction force exerted by the user. The anti-recovery of the band is in the space just above the outlet passage, vertically gripping and traction on the format constituting the end of the strip.

L'utilisateur n'a plus à aller chercher la bande devenue inaccessible dans le module, ce qui lui éviter des manipulations fastidieuses. L'invention offre donc un plus grand confort d'utilisation. L'invention est simple à mettre en oeuvre et efficace pour tous types de matériaux d'essuyage, quelle que soit l'épaisseur du matériau et ses caractéristiques spécifiques.The user no longer has to go for the band that has become inaccessible in the module, which avoids tedious manipulations. The invention therefore offers a greater comfort of use. The invention is simple to implement and effective for all types of wiping materials, regardless of the thickness of the material and its specific characteristics.

Sur les figures 1 à 10 est représenté un distributeur 1 de matériau d'essuyage prédécoupé, sous forme de bobine B déroulable en bande S.On the Figures 1 to 10 there is shown a dispenser 1 of pre-cut wiping material, in the form of a B roll-off roll in an S-band.

Le fonctionnement global du distributeur 1 est décrit par exemple dans FR2986957 . Les caractéristiques propres à l'invention sont détaillées ci-après.The overall operation of the distributor 1 is described for example in FR2986957 . The characteristics of the invention are detailed below.

Dans un but de repérage dans l'espace, une direction verticale est définie de haut en bas, une direction longitudinale est définie d'avant en arrière, et une direction transversale est définie de gauche à droite.For spatial tracking purposes, a vertical direction is defined from top to bottom, a longitudinal direction is defined from front to back, and a transverse direction is defined from left to right.

Le distributeur 1 comprend un carter 2, un couvercle 3 et un module 4. Le carter 2 est prévu pour être fixé à un support, par exemple un mur. Le carter 2 définit un logement de réception du module 4. Le couvercle 3 est articulé en partie basse sur le carter 2. Le couvercle 3 est mobile par rapport au carter 2 entre une position ouverte et une position fermée. Le module 4 est positionné dans le carter 2 lorsque le couvercle 3 est en position ouverte. Le module 4 est partiellement recouvert par le couvercle 3 en position fermée. Un passage de sortie P, prévu pour la délivrance de la bande S hors du distributeur 1, est alors délimité en partie inférieure du module 4.The distributor 1 comprises a housing 2, a cover 3 and a module 4. The housing 2 is intended to be fixed to a support, for example a wall. The housing 2 defines a receiving housing of the module 4. The cover 3 is hinged at the bottom on the housing 2. The cover 3 is movable relative to the housing 2 between an open position and a closed position. The module 4 is positioned in the casing 2 when the lid 3 is in the open position. The module 4 is partially covered by the lid 3 in the closed position. An output passage P, intended for the delivery of the band S out of the distributor 1, is then delimited in the lower part of the module 4.

Le module 4 comprend deux parois latérales 5, un dispositif de guidage 6, un dispositif de tirage 7, un volet 8 et une plaque frontale 9. Un espace E de guidage et serrage de la bande S est délimité entre le volet 8 et la plaque 9. L'espace E présente une configuration variable, en fonction de la position relative entre le volet 8 et la plaque 9. L'espace E est situé immédiatement en amont du passage de sortie P de la bande S.The module 4 comprises two lateral walls 5, a guiding device 6, a pulling device 7, a flap 8 and a front plate 9. A space E for guiding and clamping the band S is delimited between the flap 8 and the plate 9. The space E has a variable configuration, depending on the relative position between the flap 8 and the plate 9. The space E is located immediately upstream of the outlet passage P of the S-band.

Les parois 5 sont sensiblement planes et parallèles entre elles. La bobine B est positionnée entre les parois 5, sur l'arrière du module 4. La bobine B est montée sur deux embouts, non représentés dans un but de simplification. Chaque paroi 5 comportant deux logements traversant 56, prévus pour supporter le volet 8.The walls 5 are substantially flat and parallel to each other. The coil B is positioned between the walls 5, on the rear of the module 4. The coil B is mounted on two end pieces, not shown for simplification purposes. Each wall 5 having two through-housing 56, provided to support the flap 8.

Le dispositif de guidage 6 est prévu pour guider la bande S déroulée depuis la bobine B entre les parois 5, jusqu'à l'espace E. Le dispositif 6 comprend deux bras latéraux 61 et un arbre transversal 62 dont les extrémités sont supportées par les bras 61. L'arbre 62 reçoit la bande S en appui. Les bras 61 ont un mouvement de balancier au-dessus des parois 5, de sorte que l'arbre 62 est mobile au-dessus du volet 8 et de la plaque 9, et donc au-dessus de l'espace E.The guiding device 6 is provided to guide the web S unwound from the reel B between the walls 5, to the space E. The device 6 comprises two lateral arms 61 and a transverse shaft 62 whose ends are supported by the arm 61. The shaft 62 receives the band S in support. The arms 61 have a rocking movement above the walls 5, so that the shaft 62 is movable above the flap 8 and the plate 9, and thus above the space E.

Le dispositif de tirage 7 est prévu pour tirer la bande S vers le passage de sortie P, à travers l'espace E, notamment lorsque la bande S se déchire trop haut et n'est plus accessible au niveau du passage P. Le dispositif 7 comprend deux bras latéraux 71, un galet 72, un levier 73, et un mécanisme non représenté dans un but de simplification. Le dispositif 7 est décrit plus en détail dans FR2986957 .The pulling device 7 is provided to pull the band S towards the outlet passage P, through the space E, in particular when the band S tears too high and is no longer accessible at the passage P. The device 7 comprises two lateral arms 71, a roller 72, a lever 73, and a mechanism not shown for purposes of simplification. The device 7 is described in more detail in FR2986957 .

Grâce à l'invention, la présence du dispositif 7 dans le module 4 est optionnelle.Thanks to the invention, the presence of the device 7 in the module 4 is optional.

Le volet 8 est disposé transversalement et verticalement entre les parois latérales 5. Le volet 8 comporte une face avant 81, une face arrière 82, une bordure supérieure 83, une bordure inférieure 84 et deux bordures latérales 85. La face avant 81 est disposée en regard de la plaque 9, tandis que la face arrière 82 est disposée en regard de la bobine B. Les bordures latérales 85 s'étendent sensiblement verticalement, en regard des parois latérales 5. La bordure inférieure 84 comporte une ouverture centrale 87.The flap 8 is arranged transversely and vertically between the side walls 5. The flap 8 comprises a front face 81, a rear face 82, an upper edge 83, a bottom edge 84 and two side edges 85. The front face 81 is arranged in view of the plate 9, while the rear face 82 is disposed facing the coil B. The lateral edges 85 extend substantially vertically, facing the side walls 5. The lower edge 84 has a central opening 87.

Quatre tiges transversales 86 sont formées en saillie sur les bordures latérales 85. Plus précisément, chaque bordure 85 comporte deux tiges 86 espacées, situées respectivement en partie haute et en partie basse du volet 8. Les tiges 86 sont reçues dans les parois 5, qui supportent alors le volet 8.Four transverse rods 86 are formed projecting on the side edges 85. More specifically, each edge 85 has two spaced rods 86, located respectively in the upper part and in the lower part of the flap 8. The rods 86 are received in the walls 5, which then support shutter 8.

La face avant 81 comporte un profil en arc-en-ciel 88, constitué de saillies 881 et creux 882 en alternance. Chaque saillie 881 et chaque creux 882 s'étend suivant un arc sur la face avant 81. Le profil 88 a deux extrémités inférieures 883 débouchant au niveau de la bordure 85.The front face 81 has a rainbow profile 88, consisting of projections 881 and recess 882 alternately. Each protrusion 881 and each recess 882 extends in an arc on the front face 81. The profile 88 has two lower ends 883 opening at the edge 85.

De part et d'autre de l'ouverture 87, le volet 8 comporte des pointes 89 dirigées vers l'avant. Les pointes 89 sont prévues pour favoriser la déchirure de la bande S prédécoupée. Ainsi, l'utilisateur tirant sur la bande S prend une unique feuille de matériau, tandis que le reste de la bande S reste dans l'espace E.On either side of the opening 87, the flap 8 has points 89 directed towards the front. Tips 89 are provided to promote tearing of the S-band Pluck. Thus, the user pulling on the band S takes a single sheet of material, while the rest of the band S remains in the space E.

En variante non représentée, les pointes 89 peuvent être disposées sur une pièce complémentaire, fixée au volet 8 au niveau de l'ouverture 87.As a variant not shown, the tips 89 may be arranged on a complementary piece, fixed to the flap 8 at the opening 87.

Selon une autre variante, les pointes 89 peuvent être remplacées par un élément en matériau adhérent, par exemple en élastomère, augmentant localement les frottements entre la bande S et le volet 8.According to another variant, the tips 89 may be replaced by an element of adherent material, for example elastomer, locally increasing the friction between the band S and the flap 8.

La plaque 9 est disposée transversalement en avant du volet 8 et articulé sur les parois 5. La plaque 9 mobile par rapport aux parois 5 entre une position abaissée et une position relevée. La plaque 9 comporte une face avant 91, une face arrière 92, une bordure supérieure 93, une bordure inférieure 94 et deux bordures latérales 95. Lorsque la plaque 9 est relevée, la face avant 91 est disposée en regard de l'utilisateur du distributeur 1, tandis que la face arrière 92 est disposée en regard du volet 8. Des charnières 96 sont formées entre les bordures 94 et 95, de part et d'autre de la plaque 9, pour son articulation sur les parois 5. La bordure inférieure 94 comporte une ouverture centrale 97.The plate 9 is arranged transversely in front of the flap 8 and articulated on the walls 5. The plate 9 movable relative to the walls 5 between a lowered position and a raised position. The plate 9 has a front face 91, a rear face 92, an upper edge 93, a bottom edge 94 and two side edges 95. When the plate 9 is raised, the front face 91 is arranged facing the user of the distributor. 1, while the rear face 92 is disposed opposite the flap 8. Hinges 96 are formed between the edges 94 and 95, on either side of the plate 9, for its articulation on the walls 5. The lower edge 94 has a central opening 97.

La face arrière 92 comporte un profil en arc-en-ciel 98 constitué de saillies 981 et creux 982 en alternance. Chaque saillie 981 et chaque creux 982 s'étend suivant un arc sur la face arrière 92. Le profil 98 a deux extrémités inférieures 983 débouchant au niveau de la bordure 85.The rear face 92 has a rainbow profile 98 consisting of projections 981 and hollow 982 alternately. Each protrusion 981 and each recess 982 extends in an arc on the rear face 92. The profile 98 has two lower ends 983 opening at the edge 85.

De part et d'autre de l'ouverture 97, l'une des saillies 981 présente une largeur croissante à chacune des extrémités 983. Cette saillie 981 forme ainsi une pointe 983 dirigée vers le volet 8. Comme les pointes 89, les pointes 983 sont prévues pour favoriser la déchirure de la bande S prédécoupée. Ainsi, l'utilisateur tirant sur la bande S prend une unique feuille de matériau, tandis que le reste de la bande S reste dans l'espace E.On either side of the opening 97, one of the projections 981 has an increasing width at each of the ends 983. This projection 981 thus forms a point 983 directed towards the flap 8. Like the tips 89, the tips 983 are provided to promote the tearing of the precut tape S. Thus, the user pulling on the band S takes a single sheet of material, while the rest of the band S remains in the space E.

En variante non représentée, les pointes 983 peuvent être disposées sur une pièce complémentaire, fixée à la plaque 9 au niveau de l'ouverture 97.Alternatively not shown, the tips 983 may be arranged on a complementary piece, fixed to the plate 9 at the opening 97.

Selon une autre variante, les pointes 983 peuvent être remplacées par un élément en matériau adhérent, par exemple en élastomère, augmentant localement les frottements entre la bande S et la plaque 9.According to another variant, the tips 983 may be replaced by an element of adherent material, for example elastomer, locally increasing the friction between the band S and the plate 9.

Les ouvertures centrales 87 et 97 sont disposées en regard. Lorsque la plaque 9 est relevée, les ouvertures 87 et 97 délimitent le passage de sortie P, immédiatement en dessous de l'espace E.The central openings 87 and 97 are arranged facing each other. When the plate 9 is raised, the openings 87 and 97 delimit the outlet passage P, immediately below the space E.

Les profils en arc-en-ciel 88 et 98 sont complémentaires. Lorsque la plaque 9 est relevée, les saillies 881 sont logées dans les creux 982 et les saillies 981 sont logées dans les creux 882. Les profils 88 et 98 délimitent entre eux l'espace E de guidage et serrage de la bande S.The rainbow profiles 88 and 98 are complementary. When the plate 9 is raised, the projections 881 are housed in the recesses 982 and the projections 981 are housed in the recesses 882. The profiles 88 and 98 delimit between them the space E for guiding and clamping the band S.

Selon l'invention, le module 4 comprend un système de débattement 10 relatif entre le volet 8 et la plaque 9, faisant varier la configuration de l'espace E de guidage et serrage de la bande S.According to the invention, the module 4 comprises a relative displacement system 10 between the flap 8 and the plate 9, varying the configuration of the space E for guiding and clamping the band S.

Le système de débattement 10 comprend les quatre logements 56 ménagés dans les parois 5 et les quatre tiges 86 formées en saillie sur les bordures 85 du volet 8. Chaque logement 56 reçoit l'une des tiges 86.The deflection system 10 comprises the four housings 56 formed in the walls 5 and the four rods 86 projecting on the edges 85 of the flap 8. Each housing 56 receives one of the rods 86.

Chaque logement 56 présente une section non circulaire. Plus précisément, chaque logement 56 a une section en L, avec une partie longitudinale 57 et une partie verticale 58. Ainsi, un jeu est défini entre chaque tige 86 et le bord intérieur du logement 56 correspondant, à la fois longitudinalement et verticalement.Each housing 56 has a non-circular section. Specifically, each housing 56 has an L-shaped section, with a longitudinal portion 57 and a vertical portion 58. Thus, a clearance is defined between each rod 86 and the inner edge of the housing 56 corresponding, both longitudinally and vertically.

Par conséquent, le volet 8 présente une mobilité longitudinale et une mobilité verticale entre les parois 5. Ces mobilités sont limitées par le contact de butée entre les tiges 86 et les bords des logements 56.Therefore, the flap 8 has a longitudinal mobility and a vertical mobility between the walls 5. These mobilities are limited by the abutment contact between the rods 86 and the edges of the housing 56.

Le système de débattement 10 comprend en outre deux ressorts 100 disposés de chaque côté du module 4, contre la face extérieure des parois 5. Chaque ressort 100 a une extrémité supérieure 101 et une extrémité inférieure 102. L'extrémité 101 est accrochée à une proéminence 59 formée sur la paroi 5, tandis que l'extrémité 102 est accrochée à l'une des tiges 86 du volet 8.The deflection system 10 further comprises two springs 100 disposed on each side of the module 4, against the outer face of the walls 5. Each spring 100 has an upper end 101 and a lower end 102. The end 101 is attached to a prominence 59 formed on the wall 5, while the end 102 is attached to one of the rods 86 of the flap 8.

Les ressorts 100 sont positionnés en biais. Les ressorts 100 exercent un effort tendant à ramener le volet 8 vers le haut et l'avant, et ainsi resserrer verticalement et longitudinalement l'espace E délimité entre le volet 8 et la plaque 9.The springs 100 are positioned at an angle. The springs 100 exert a force tending to bring the shutter 8 upwards and forwards, and thus to tighten vertically and longitudinally the space E delimited between the shutter 8 and the plate 9.

En variante non représenté, les ressorts 100 sont positionnés longitudinalement. Les ressorts 100 exercent alors un effort tendant à ramener le volet 8 vers l'avant, et ainsi resserrer longitudinalement l'espace E.In variant not shown, the springs 100 are positioned longitudinally. The springs 100 then exert a force tending to bring the shutter 8 forward, and thus tighten longitudinally the space E.

Selon une autre variante non représentée, les ressorts 100 sont positionnés verticalement. Les ressorts 100 exercent alors un effort tendant à ramener le volet 8 vers le haut, et ainsi resserrer verticalement l'espace E.According to another variant not shown, the springs 100 are positioned vertically. The springs 100 then exert a force tending to bring the shutter 8 upwards, and thus vertically tighten the space E.

Selon une autre variante non représentée, le système 10 est dépourvu de ressorts 100. Dans ce cas, l'espace E est resserré par gravité, sous le poids propre du volet 8.According to another variant not shown, the system 10 is devoid of springs 100. In this case, the space E is constricted by gravity, under the own weight of the flap 8.

De préférence, le système de débattement 10 comprend un dispositif de réglage 110 en position transversale du volet 8 entre les parois latérales 5.Preferably, the deflection system 10 comprises an adjustment device 110 in transverse position of the flap 8 between the side walls 5.

Comme les logements 56 traversent les parois 5 de part en part, les tiges 86 peuvent se déplacer transversalement dans les logements 56. Ainsi, le volet 8 présente une mobilité transversale entre les parois 5. Cette mobilité est limitée par le contact de butée entre les bordures 85 et les parois 5. Autrement dit, le jeu prévu entre chaque tige 86 et le logement 56 correspondant est également transversal.As the housings 56 traverse the walls 5 from one side to the other, the rods 86 can move transversely in the housings 56. Thus, the flap 8 has a transverse mobility between the walls 5. This mobility is limited by the abutment contact between the curbs 85 and the walls 5. In other words, the clearance provided between each rod 86 and the corresponding housing 56 is also transverse.

Le dispositif de réglage 110 est actionnable par un opérateur. Le dispositif de réglage 110 comprend une plaquette 111 et une vis 112. La plaquette 111 est en appui contre l'une des tiges 86 du volet 8. De préférence, la plaquette 111 comporte une cavité borgne recevant cette tige 86. La vis 112 traverse la plaquette 111 et pénètre dans la paroi 5. Sous l'action d'un vissage de la vis 112 dans la paroi 5, la plaquette 111 appuie contre la tige 86. Le volet 8 est déplacé transversalement, ce qui modifie transversalement l'espace E entre le volet 8 et la plaque 9.The adjustment device 110 is operable by an operator. The adjustment device 110 comprises a plate 111 and a screw 112. The plate 111 bears against one of the rods 86 of the flap 8. Preferably, the plate 111 comprises a blind cavity receiving this rod 86. The screw 112 crosses the plate 111 and enters the wall 5. Under the action of screwing the screw 112 in the wall 5, the plate 111 bears against the rod 86. The flap 8 is moved transversely, which transversely modifies the space E between the flap 8 and the plate 9.

En pratique, le système de débattement 10 permet de resserrer temporairement l'espace E délimité entre le volet 8 et la plaque 9, et donc augmenter temporairement les forces de frottements exercées entre la bande S, le volet 8 et la plaque 9 dans cet espace E, lorsqu'un utilisateur tire sur la bande S. Les forces de frottement sont conjuguées à la force de tirage pour séparer un format de la bande S dans l'espace E. Ce format est alors tiré par l'utilisateur au niveau du passage de sortie P. En outre, ces forces de frottement empêchent la bande S de remonter en direction de la bobine B, en serrant la bande S dans l'espace E.In practice, the deflection system 10 makes it possible to temporarily tighten the space E delimited between the flap 8 and the plate 9, and thus temporarily increase the friction forces exerted between the strip S, the flap 8 and the plate 9 in this space E, when a user pulls on the S-band. The friction forces are combined with the pulling force to separate a format of the S-band in the space E. This format is then pulled by the user at the passage In addition, these friction forces prevent the band S from going up towards the coil B, by tightening the band S in the space E.

D'autres modes de réalisation de l'invention sont montrés aux figures 11 à 13. Certains éléments constitutifs du distributeur 1 sont comparables à ceux du premier mode de réalisation décrit plus haut et, dans un but de simplification, portent les mêmes références numériques.Other embodiments of the invention are shown in Figures 11 to 13 . Some constituent elements of the distributor 1 are comparable to those of the first embodiment described above and, for the sake of simplification, bear the same numerical references.

Sur la figure 11, le dispositif de réglage 110 comprend un filetage 116 formé sur l'une des tiges 86 du volet 8, un boulon 117 positionné sur cette tige 86, et un ressort 118 interposé entre le boulon 117 et la bordure 85 du volet 8. Sous l'action d'un vissage du boulon 117 sur la tige 86, le ressort 118 est comprimé contre la bordure 85 et la tige 86 se translate transversalement. Le volet 8 est déplacé transversalement, ce qui modifie transversalement l'espace E entre le volet 8 et la plaque 9.On the figure 11 , the adjusting device 110 comprises a threading 116 formed on one of the rods 86 of the flap 8, a bolt 117 positioned on this rod 86, and a spring 118 interposed between the bolt 117 and the edge 85 of the flap 8. Under By screwing the bolt 117 onto the rod 86, the spring 118 is compressed against the rim 85 and the rod 86 translates transversely. The flap 8 is moved transversely, which transversely modifies the space E between the flap 8 and the plate 9.

Sur la figure 12, les extrémités inférieures 883 du profil en arc-en-ciel 88 sont orientées à 45 degrés et ne débouchent pas au niveau de la bordure 84. De même, les extrémités inférieures 983 du profil en arc-en-ciel 98 sont orientées à 45 degrés et ne débouchent pas au niveau de la bordure 94.On the figure 12 , the lower ends 883 of the rainbow profile 88 are oriented at 45 degrees and do not open at the edge 84. Similarly, the lower ends 983 of the rainbow profile 98 are oriented at 45.degree. degrees and do not open at the edge 94.

Sur la figure 13, montrant uniquement le volet 8, les extrémités 883 sont également orientées à 45 degrés. Le profil 88 présente une partie supérieure curviligne 885 et deux parties supérieures rectilignes 886.On the figure 13 , showing only the flap 8, the ends 883 are also oriented at 45 degrees. The profile 88 has a curvilinear upper portion 885 and two rectilinear upper portions 886.

Dans les modes de réalisation des figures 12 et 13, l'espace E présente une configuration différente, mais un découpage de la bande S au moins aussi efficace, en comparaison avec le premier mode de réalisation décrit plus.In the embodiments of Figures 12 and 13 the space E has a different configuration, but a cutting of the band S at least as effective, compared with the first embodiment described more.

Par ailleurs, le distributeur 1 peut être conformé différemment des figures 1 à 13 sans sortir du cadre de l'invention. En outre, les caractéristiques techniques des différents modes de réalisation et variantes mentionnés ci-dessus peuvent être, en totalité ou pour certaines d'entre elles, combinées entre elles. Ainsi, le distributeur 1 peut être adapté en termes de coût, d'ergonomie, de fonctionnalités et de performance.Moreover, the distributor 1 may be shaped differently from the Figures 1 to 13 without departing from the scope of the invention. In addition, the technical characteristics of the various embodiments and variants mentioned above may be, in whole or in part, combined with one another. Thus, the dispenser 1 can be adapted in terms of cost, ergonomics, functionality and performance.
